The JCM900, released around the same time, is probably more "iconic" than the Diezel or the Bogner.I don't know, I wouldn't consider the
Diezel VH4 and Bogner Ecstasy 100A/B to be "iconic" to anyone outside of the (relatively) small subset of metal guitar players. Wheras anyone with even a passing interest in guitar amps knows about the 5150 and a Dual Rec.
It's kind of like how the Fender Princeston and 6G15 are absolutely legendary in the surf community, but not really a big deal outside that circle.
